1 Claim.

The invention relates to a cable connector, and 13-.5

more especially to a power line bridle connection.

The primary object of the invention is the provision of a connection ofthis character, wherein a bridle-power sealed connection is madeconnecting two or more feeder lines or cables r tension lines on highpower or solid cables, the connection being novel in construction andunique in the assembly thereof.

Other objects of the invention are the provision of a connection of thischaracter, for tapping feed lines to boost power on trolley lines thatextend to other sections or territories, the provision of a connectionthe terminals of which are sealed and held firmly and the provision of aconnection that can be installed with ease and dispatch.

A further object of the invention is the provision of a connection ofthis character, wherein slipping, erosion or the accumulation of dust,particularly in mines will be prevented, and the anchoring of the cablesor lines is accomplished with surety.

A still further object of the invention is the provision of a connectionof this character, which is simple in construction, thoroughly reliableand efiicient in purpose, strong, durable, readily and easily installed,assuring safety, and inexpensive to manufacture and install.

With ..these and other objects in view the invention consists in thefeatures of construction, combination and arrangement of parts as willbe hereinafter more fully described, illustrated in the accompanyingdrawings, which disclose the preferred embodiments of the invention andpointed out in the claim hereunto appended.

In the accompanying drawings:

Figure 1 is a side elevation of the bridle connection constructed inaccordance with the invention;

Figure 2 is a vertical longitudinal sectional view therethrough;

Figure 3 is a sectional view taken on the line 33 of Figure 1 looking inthe direction of the arrows;

Figure 4 is a sectional view taken on the line 4-4 of Figure 1 lookingin the direction of the arrows;

Figure 5 is'a sectional view taken on the line 55 of Figure 1 looking inthe direction of the arrows;

Figure 6 is a view similar to Figure 1 partly in section showing aslight modification;

Figure 7 is a view similar to Figure 6 showing a further modification;

Figure 8 is a sectional view taken on the line 88 of Figure 7 looking inthe direction of the arrows.

Similar reference, characters indicate corresponding parts throughoutthe several views in the drawings.

Referring to the drawings in detail, particularly Figures 1 to 5inclusive, the connection constituting the present invention, comprisesa bridle member designated generally at A in its entirety, involving apair of spaced tubiform terminal portions II], which are in axialalignment with each other and united in their spaced relation to eachother by slight outwardly arched coupling webs I I, which are disposeduniformly spaced concentrically about the portions I0, with outwardlytapered areas I2 merging into such terminals, and the spacing of theseportions create therebetween a vacancy I3.

The terminal portions III are formed with outwardly tapered bores I4,which are reversed to each other in said portions for accommodatingplural longitudinally split wedging sleeve-like keys I5, these beingexternally tapered correspondingly to the bores I4, while havinginternal straight central passages I6 therethrough, into which arereceived the stripped ends I! of covered insulated cables 18, as bestseen in Figures 1 and 2 of the drawings, and thus creating a bridlepowersealed connection between two feeder tension lines, yet it may be usedfor other purposes, for instance, tension lines on high power or solidcables not shown.

Sufiicient keys I5 are used to make a complete encirclement of the cableinside of the terminal portion II] of the bridle connection. In thepresent invention three keys are sufiicient to make a completeencirclement of the cable but in some instances the keys may be reducedin size so that more keys are required. Each key is to he slipped overits cable end I'I after the latter has been passed into the portion ll)of the bridle and when all the keys have been inserted in the portionID, with a pull on the cables I8 and a concurrent tap with a hammer orother like implement on the keys Hi the latter will become firmlyembedded in the bridle and the cables will be ready to be drawn taut forthe stringing thereof.

In Figure 6 of the drawings there is shown a slight modification of theinvention, wherein only one cable I9 is gripped, while opposite theretothe key 20 is of insulated material, and has swiveled thereinlongitudinally of the same an eye anchoring member 2|.

In Figures 7 and 8 of the drawings there is shown a further modificationof the invention,

wherein the cable 22 has a cleared insulating area 23 on which issuperimposed a saddling crown 24, with an intermediate block like head25, having parallel with the area 23 wedging keys 26 accommodating theend 21 of tapped in feed line 28, the crown being made from copper andsimilarly the said block. The crown 24 at opposite ends beyond the block25 is wrapped with elastic tape 29 so as to preferably prevent slipping,erosion or other accumulation of dust, particularly in mines or thelike. The crown is preferably flexible.

The ends I l of the cables may be wrapped with fine copper wire, ifdesired, and soldered ito prevent fraying the wiring being not shown.

What is claimed is:

In combination, a first cable, a fiexiblesaddling crown having anarcuate seat for receiving lengthwise said cable, removable adhesivemeans anchoring said crown to said cable, a block extending transverselyfrom said crown, a frustoconical bore in said block, a second cablehaving the terminal thereof in said bore, a pluralityof tapered wedgemembers in said bore slidabl engaging the walls thereof andcircumferentially spaced about said second cable terminal frictionallyembracin the same, whereby relative movement or any tendency thereto toseparate said block and said second cable terminal 'rela- V tively toeach other will cause said tapered wedges to firmly grip said secondcable.
